Body weight, dietary intake, and health risk factors pre-COVID and during the COVID-19 pandemic.

The objective of this study was to assess changes in body weight, body fat, food intake, and clinical risk factors during the 2020 COVID-19 pandemic (COVID group) vs. the pre-COVID period (pre-COVID group). Clinical measurements were collected and Food Frequency Questionnaires (FFQs) were administered at two time points for each group (211 days ± 114 SD). For the pre-COVID group, the data were collected before February 20, 2020. For the COVID group, the data were collected either before and after February 20, 2020, or both between February 20, 2020 and April 1, 2021, excluding a 6.5-month pandemic-related pause of hospital visits. Increases in the following outcome measures were seen in the COVID group relative to the preCOVID group: body weight (t = 3.40, p = 0.004), body fat mass (t = 2.29, p = 0.024), diastolic blood pressure (BP) (t = 2.10, p = 0.039), total cholesterol (t = 1.81, p = 0.074, marginal), and fat/oil intake (t = 2.44, p = 0.017). In contrast, there were decreases in fruit intake (t = -1.88, p = 0.064, marginal) in the COVID group compared to the preCOVID group. The COVID period relative to pre-COVID was associated with unfavorable changes in body weight and composition, food intake, and health risk factors. This appears to be the first report of in-person direct measures of changes in body weight and risk factors.

Changes in food intake during the COVID-19 pandemic in New York City.

The COVID-19 pandemic and stay-at-home orders across the nation have had substantial consequences on access to food and dietary behaviors. We investigated the dietary intake of adults in NYC, before and during the COVID-19 period. A subset of participants (n = 31) from an NIH-funded multi-level discount supermarket study were assessed. In this study, the experimental groups received a 0% (control), 15%, or 30% discount on fruits, vegetables, and noncaloric beverages for 8 months. The discount level for the participants who were selected for this study did not change from the pre-COVID to during COVID periods. Dietary intake data was collected using three unannounced 24-h dietary recalls (2 weekdays, 1 weekend) during each period. Changes in total daily kcal of food and beverages, total g of solid food, energy density of solid food (kcal/g), and g of fruit and vegetables, soda, non-caloric beverages, and snack foods were analyzed using multivariate linear regression. Energy density (ED) increased during COVID (+0.02 ± 0.5 [SD], F[4,26] = 3.0, p = 0.038). There was an interaction by gender (t = -3.2, p = 0.0035) such that ED increased for females (+0.27 ± 0.46, p = 0.037) and decreased for males (-0.22 ± 0.32, p = 0.012). The change in ED is likely due to the circumstances surrounding COVID-19, e.g. being at home, stress, and food shortages.
